快速搭建SSM框架（基于IDEA+Maven)

桃扇骨 2023-10-11 19:48 6阅读 0赞

环境所需：JDK1.8、IDEA、Maven、MySQL5.7及以上等

引言：手把手教大家基于IDEA的maven环境搭建一个SSM框架、请事先装好所需要的软件工具等，SSM+Java+Maven+JSP，SSM整合JSP，mapper和实体层使用的是自动生成噢！

Java环境搭建教程：浏览器搜索https://www.bilibili.com/video/BV1BN4y1c7Fp/

以下是完整的框架案例！可以在上面上进行修改！

1、打开idea，新建Project，选择Maven、勾选骨架，并选中maven-archetype-webapp之后，点击next

2、创建GroupId（包名）com.flight,ArtifactId（项目名称）flight\_web,然后点击next

![f417cb12d1b1c1f0c079166f8a052f1b.png][]

3、选择maven的安装目录，并配置setting.xml,然后点击next，如果没有搭建maven，请搜索：https://www.bilibili.com/video/BV1BN4y1c7Fp/

4、选择安装目录，放到D盘，然点击Finish

5、open打开项目之后，在main目录下创建两个dirctory（包），分别是java和resources文件夹。

6、点击java包右击选择Mark Directory as -->Sources Root，然后 选择resouces包右击右击选择Mark Directory as -->Resources Root，就编程下面的样子了，需要手动操作的！

7、配置pom文件,在maven的pom文件配置下面的jar，然后点击Import Changes

      <build>    <finalName>website</finalName>    <plugins>      <plugin>        <groupId>org.apache.tomcat.maven</groupId>        <artifactId>tomcat7-maven-plugin</artifactId>        <version>2.2</version>        <configuration>          <path>/</path>          <port>8080</port>        </configuration>      </plugin>      <plugin>        <groupId>org.mybatis.generator</groupId>        <artifactId>mybatis-generator-maven-plugin</artifactId>        <version>1.3.7</version>        <configuration>          <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>          <overwrite>true</overwrite>          <verbose>true</verbose>        </configuration>      </plugin>    </plugins>    <resources>      <resource>        <directory>src/main/java</directory>        <includes>          <include>**/*.xml</include>        </includes>      </resource>      <resource>        <directory>src/main/resources</directory>        <includes>          <include>**/*.*</include>        </includes>      </resource>    </resources>  </build></project>

8、配置webapp下的WEB-INF下的web.xml文件，把下面的复制过去，并在WEB-INF下面建一个jsp的目录，解析的界面放在jsp目录里面。

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  <display-name>flight_web</display-name>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <filter>    <filter-name>CharacterEncodingFilter</filter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    <init-param>      <param-name>encoding</param-name>      <param-value>UTF-8</param-value>    </init-param>  </filter>  <filter-mapping>    <filter-name>CharacterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>
        <servlet>    <servlet-name>DispatcherServlet</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:springmvc.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>DispatcherServlet</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <error-page>    <error-code>404</error-code>    <location>/WEB-INF/jsp/error.jsp</location>  </error-page></web-app>

9、在resources目录下面配置applicationContext.xml文件，这个是Spring的配置文件。

![4d5f8a2468ffc6f237317c7a38ce4d30.png][]

10、在resources目录下面配置db.propretie文件，这个是数据库的配置文件。

jdbc.driver=com.mysql.cj.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/db_flight_web?useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true&useUnicode=true&characterEncoding=utf-8jdbc.username=rootjdbc.password=123456

11、接着在resources目录下面配置generatorConfig.xml文件，这个是对象映射框架的配置文件，可以生成自动生成mapper和实体类，不需要手动创建。

注意：将mysql-connector-java-5.1.46.jar放到D盘里面，可以是其他版本的，不然无法自动生成！

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration>        <classPathEntry  location="D:\mysql-connector-java-5.1.46.jar"/>    <context id="DB2Tables"  targetRuntime="MyBatis3">        <commentGenerator>            <property name="suppressDate" value="true"/>                        <property name="suppressAllComments" value="true"/>        </commentGenerator>                <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/db_flight_web"                        userId="root" password="123456">        </jdbcConnection>        <javaTypeResolver>            <property name="forceBigDecimals" value="false"/>        </javaTypeResolver>                <javaModelGenerator targetPackage="com.flight.entity" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>            <property name="trimStrings" value="true"/>        </javaModelGenerator>                <sqlMapGenerator targetPackage="com.flight.mapper" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </sqlMapGenerator>                <javaClientGenerator type="XMLMAPPER" targetPackage="com.flight.mapper" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </javaClientGenerator>        
    
    
            <table tableName="t_admin" domainObjectName="Admin">            <property name="useActualColumnNames" value="true"></property>        </table>
    
    
            </context></generatorConfiguration>

12、接着在resources目录下面配置log4j.properties文件，这个是配置日志文件。

log4j.rootLogger=DEBUG, Console  #Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppender  log4j.appender.Console.layout=org.apache.log4j.PatternLayout  log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  log4j.logger.java.sql.ResultSet=INFO  log4j.logger.org.apache=INFO  log4j.logger.java.sql.Connection=DEBUG  log4j.logger.java.sql.Statement=DEBUG  log4j.logger.java.sql.PreparedStatement=DEBUG

13、接着在resources目录下面配置springmvc.xml文件，这个是配置SpringMVC的配置文件。

*  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *

 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *  
 *

14、接着在resources目录下面配置SqlMapConfig.xml文件，配置分页插件，和驼峰设置！

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>  <settings>       <setting name="mapUnderscoreToCamelCase" value="true"/>   </settings>  <plugins>        <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>  </plugins></configuration>

15、配置LoginIntercepter进行登录拦截！,比如只有登录之后才可以访问后台，如果没有登录则不可以访问！

package com.flight.intercepter;
    import com.flight.entity.Admin;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;
    import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;
    
    public class LoginIntercepter implements HandlerInterceptor {
           @Override    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
       
            // 获取请求的URL        String url = request.getRequestURI();        // URL:除了login.jsp是可以公开访问的，其它的URL都进行拦截控制        if(url.indexOf("/login")>=0){
                   return true;        }        // 获取Session        HttpSession session = request.getSession();        Admin admin = (Admin) session.getAttribute("admin");        // 判断Session中是否有用户数据，如果有，则返回true,继续向下执行        if(admin != null){
                   return true;        }        // 不符合条件的给出提示信息，并转发到登录页面        request.setAttribute("msg", "您还没有登录，请先登录！");        request.getRequestDispatcher("/WEB-INF/jsp/login.jsp")                .forward(request, response);        return false;
        }
        @Override    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
       
        }
        @Override    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
       
        }}

16、自动生成实体和mapper，双击mybaits-generator:generate！即可生成！

![7327892d7cbc0f6582d233c29c670e8c.png][]

17、配置tomcat使用自带插件，双击tomcat7:run即可，非常快速，然后访问路径进入到登陆界面！

本次以Admin实体作为另一个案例，完成了一个登录功能，请自行领取！
